APPARATUS FOR USE IN MANUFACTURING ARTICLES OF CERAMIC MATERIAL.

' Application filed January 31, 1914.

Articles of Ceramic Material, of which the following is a specification.

This invention relates to improved apparatus for use in manufacturing articles of ceramic material.

Heretofcre in the manufacture of porcelain articles, such as spark plugs, insulators.

faucet handles, and the like, it'has been the common practice to place a mass of the plastic clay upon a rapidly revolving table, the material being, roughly shaped by hand. to the desired form so as to provide blanks. Said blanks are allowed to stand until. they reach what is known as green or half ha rd condition. .This preliminary shaping" is known as throwing. The blank whilein the green state is brought to the finished shape by being placed upon a turning lathe, the desired contour being imparted by means of suitable tools held in the hand of the operator, or otherwise positioned over the clay. After turning, the blank is allowed to dry, and then is dipped into'a suitable glaze and placed in a kiln, or placed directly into the kiln, and fired. This p 'actice results in a great percentage of loss by reason of the fact that the material has to be allowed to become white hard or bone dry after forming and before being placed in the kilnfor firing. Furthermore a. considerable variation in the dimensions of the finished or fired ware results from the fact that there is no accurate means of determin-- ing the exact time when the blank has reached the green condition, this condition depending, as it does, on the amount of water or moisture the blank may contain. Consequently, few, if any of the blanks, contain the same percentage of water or moisture when turned or given the desired contour, and whenv placed aside to'dry before firihg, a considerable variation of the dimensions will result, and accordingly a large percentage of variation in the dimensions of the finished Ware must be expected. It is ob vious that skill of the highest'order is re quired for both the throwing and the turning operations, usually in the process of Specification of Letters Patent.

turning the piece is so shaped that the cross section of some points is much heavier and more massire than the others. In some in stances cracks are formed in the drying orocess, and in others a settling and Warping occurs, due in the first instance to light sections drying more rapidly than the heavier; and in the secondcase, to the weight of the blank compressing the lighter sections unevenly.

One of the objects of the present invention is to overcome these objections by pmvision of simple and improved, mechanism for quickly and accurately shaping the blank.

it further object is to provide 2. machine ca pable of imparting the final shape to the blanks after the latter have reached. the whit hard condi n.

ii her objec is to provide improved. means for supporting the blanks during" the shaping operation.

ii. further objectis to prov de means quickly and accurately i he shaping means.

A further object is to provide means for automatically feeding the blanks to the ma chine and for successivly acting upon said eding the blanks to bring them to the desired shape, the functions of the-machine throughout, be

7' U de six drawal of the spindle until the forming or grinding operation has been completed. The instant each head 2% leaves the groove 66 it is engaged by the cam member 60 and moved to the right, thereby withdrawing the spindle from the blank. The guide 65 is also so related to the cam member {59 that immediately after said cam member has moved a spindle 33 to the right, the head 3% of said spindle is engaged by the guide 65 The parts are so related, however, that as the head 3-l of each spindle leaves the guide 65 it is engaged by the upper end of the cam member 59 and moved to the left a sufiicient distance to cause said head to engage the guide 68. In this manner the spindle is retracted to permit Withdrawal of the completed blank, and held so retracted until it leaves the guide 68 at which instant it is again engaged by the cam member 59 and moved to the right, as above described.

The, sleeves 28 and 31, and the spindles 33 are rotated by means of a belt 69 driven from any suitable source and engaging the pulleys In this manner the chucks 30 are rotated and a corresponding rotation of the blanks takes place. As the head .18 and the turrets '20 and 26 are rotated, the-blanks B are brought successively into engagement with the grinding wheel 45, and the desired contour imparted thereto in the time that the said blank is passing the said grinding wheel. Just after the grinding or shaping operation is completed the blank is engaged by the cutting disk d5 which severs the blank close to the chuck 30. At about the same time the cam members Bland engage the heads of the spindles '33 and 21, respectively, withdrawing the pointed ends of the latter from the finished blank, in the manner heretofore described. Immediately after the blank is severed by wheel 45, the cain member 63 engages the end of the sleeve 31 and forces the ejector head 32 to the right, to eject the waste portion of the blank from the chuck 30, said Waste portion droppin into asuitable chute or receptacle provided for that purpose. The operator may then remove the finished blank, and the foregoing operation will be continued as long as the blanks are supplied by the chute C. The ejector head 32 is returned to its" normal position by the action of Spindle 21 when a new blank, is placed within the chuck 30.

It will be noted that the turrets 20 and 26 are mounted Within suitable casings, and the bearings 15 are shown as of the floating type. 'That is,a suitable ball bearing 'is provided, the shaft 16 havinga collar 70 secured thereto to prevent movement of the shaft longitudinally, a bushing 71 being also mounted on the shaft. This arrangement provides a cushion on the lubricant held. be-

tween the running fits of the shaft and the.

bushing and the housingfor the latter. We do not desire to limit ourselves, however, to the particular form of bearing referred to. The shaft 40 is normally driven in a forward direction by a pulley 7 12 mounted on a bushing 73 keyed to said shaft, a second pulley Tl being secured to, or formed with said bushing.v The pulley 72 is rotated by means of a belt 75 driven by pulley 76 and. passing over idlers 7 7, 77', the former being mounted in stationary bearings, the latter being mounted in suitable bearings carried by an arm 78. Said arm is secured to a bushing 79 pivotally mounted on thcshaft 40. A weight 80 tends to normally hold the arm. 78 in such a position that the idler 77 maintains suflicient tension on the belt 75 to drive pulley 72 in a. forwardly direction. It is also desirable to have the shaft 16 travel at a greater rate of speed after a blank has been completed and in order to present the next blank to the action of the grinding wheel 45, than when the blank is actually in engagement with said grinding wheel. The pulleys 72 and Ti are arranged in the manner described, to permit of change in speed. To obtain the desired results the pulley 74 is driven by a belt actuated by a drive pulley 84, said belt being passed over idler-s the latter bcingsupported by an arm 86 carried by a sleeve a loosely mounted upon the shaft a0. Said sleeve is connected by an arm 5 with another sleeve 0 also loosely mounted on the shaft 40. Said-sleeveis pro vided with an actuating arm Z carrying an antidrictionroller arranged to engage the under sideot'a cam ring 91 secured to the edge of the crank disk ll). A spring connects arm i) withthe lever 43, the action of the spring being such as to cause the arm 86 to assume a normal position which tightens the belt 82, thereby driving I the pulley 74. Just before the blank 13 engages the shaping wheel 45 the cam 91 rocks the sleeve 0 against the tension of the spring 92, imparting a corresponding movement to the arm 86 and the idler 85', the movement being in a direction to relieve the tension of 92, whereupon the idler 85 is moved to tighten the belt 82. This drives the shaft at a higher rate'ol speed, the ratchet 80 rotating faster than the pawl 79 which latter merely slide over the teeth until the driving action of the belt is again neutralized.

It is frequently necessary to reverse the lee menace rotation of the shaft 16 and the head 18. To accomplish this a reversing pulley is provided, the same being preferably made integral with the pulley Tl, indicated at T he said reversing pulley is driven by a lelt ll operated by a pulley 95 and. passed over idlcrs 96, 96', the latter being mounted in suitable bearings carried by arm 78, the former being mounted in stationary bean ings. The action of the weight tends to normally hold the idler 96 in such position that the belt 2% remains loose that the pulley 93 is inactive. The normal position;

ot the lever 43, when the machine in operation is such that the reversing; pulley 93 is normally inactive. ll'hen it is desired to reverse'thc machine the front end 43 of the lever 48 is depre sed, thereby relieving the tension on spring 9:2, moving the idler '4'?" to a position'to render the pulley Tl inoperative and at the same time moving the idler 9G to the proper position to tighten the belt ill and drive the reversing pulley 93. it is obvious that all the )arts will cease to rotate when the lever ii? is moved to neutral position because the tension on all of the belts will be relieved.
